There is a thread in one section of this board about danger by crossing the path of a comet or debris of a died comet etc.

As far as debris, comets, asteroids etc. are moving along orbits of significant eccentricity are sources of danger - what about establishing a future rule that interplanetary flights are forbidden to cross such paths against the direction the debris etc. are going along? A flight from Earth towards Mars for example would have to avoid crossing the path of objects going from outside the earthian orbit towards the earthian orbit around the sun.

On the other hand such a rule might favour flights in the same direction as the debris, comet etc. - AFTER the object has passed perhaps.

I agree to what you say - I was merely thinking about collisions far (a lot of millions km) away from Earth similar to what happened to that one Mars probe being hit by rocks after flying by Mars in the 1960s.

Dangers to Earth or objects in LEO I didn't have in mind.

I only was thinking randomly about it under the hypothesis that there might be more and regular traffic towards Mars.
